ARP (Automotive Racing Products) makes the strongest fasteners in motorsport — head studs, main studs, rod bolts, and flexplate bolts used by every Formula 1, NHRA, NASCAR, and championship motorsport program. Aerospace-grade alloys, exact-fit machining.
Ensure your engine components are secured with the reliability of Auto Racing Products. These 5/16 ID x .550 OD chamfered flat washers are designed for high-stress applications where standard hardware simply won't suffice. Crafted from premium-grade chromoly steel, these washers provide superior load distribution and resistance to deformation under extreme heat and pressure.
Whether you are building a high-performance street engine or a dedicated track machine, using the right fasteners is critical to longevity. The chamfered design allows for a flush fit against radius-cornered bolts, preventing stress risers that can lead to fastener failure. The black oxide finish not only provides a professional look but also adds a layer of protection against rust and oxidation in demanding environments. Trust in the engineering excellence of ARP to keep your critical components locked down tight. Find all your essential racing hardware and performance parts at GGCRACING.
